Had the beginnings of an interesting discussion HERE and in a previous thread that brought me to this topic.
@fred2 brought up a good question whether a 2-digit PAO, which encodes 6 digits per scene via a 2+2+2 format, is achieving the same result as a 3-digit PO, which also encodes 6 digits per scene via a 3+3 format.
I think the answer is “yes and no.”
The end result is the same, a scene that encodes 6 digits, and the scenes may even look identical in the mind.
Say the 2-digit user has Michael Jordan, Eating, and a Camping Tent as their PAO elements in their scene. They picture their scene just as described. MJ is maybe sitting at a table, chowing down on a big tent.
Lets also say that the 3-digit user has the same person and object, Michael Jordan and the Camping Tent. Now that 3-digit user will likely imagine some sort of action or interaction between those to in order to give their scene life and make it memorable. Lets say this person also imagines Michael Jordan eating the Camping Tent. Lets even say that they picture the exact same mental scene as the PAO person, right down to the table MJ is sitting at.
The scenes may be identical and have the same end result of each encoding 6 digits… BUT, and here’s the important thing in my view… The action of “eating” is an “intentional element” for the 2-digit PAO user, but for the 3-digit PO user it is an “incidental element” of their scene.
I’d define “intentional” elements as aspects of a scene that represent information and must be specifically visualized and recalled in order to successfully encode and decode that information.
“Incidental” elements are non-representative aspects of a scene that serve to add detail or boost the memorability of a scene. They need not be carefully considered, but are more reflexive natural details that the brain fills in almost subconsciously. In both example scenes, the table that MJ is sitting at is an “incidental element.” It doesn’t encode any information and isn’t really a detail that would take any extra time or brainpower to include, it is just there as a natural part of the construction of the complete scene.
This is sort of like picturing a “car” and considering it as a single intentional element, while the details like the wheels, the color, the door handles, etc, would be considered “incidental elements” that wouldn’t count against the total “elements” needed for representing the encoded information.
When considering the effectiveness of a system, I think more weight should be given to the requirement of creating intentional elements than the fact that scenes will end up with comparable amounts of incidental elements.
So therefore, given similar fluency with a system, a 3+3 would, in my mind, cost less in terms of intentional effort than a 2+2+2.
Yes, the 3+3 would require more of an investment of one-time learning effort and be slightly more “expensive” in terms of maintenance cost to keep all of its intentional elements fluent than a 2+2+2 system would be… I suppose its up to the user to decide if that tips the balance away from the difference in ease of use.
Thoughts?
